CB400F RHS fork leg bottom - brake mounts
« on: May 06, 2020, 09:36:17 PM »
On my CB400, the right hand side (near side in UK) bottom fork leg, has the brake mounts - see pic. 

I know some CB500F's had this as an option to then upgrade to dual front discs, but is this something that was standard on some 400 bikes?  My suspicion is that the bike has had a trip down the road at some point and was replaced with a 500 fork leg, but I'm intrigued...

From memory of my 400N  calipers mount behind forks on 2 larger lugs as brake design totally different to 400/4. I think they actually stopped you too! :P
One day I'll have the time to restore it, not just talk and dream....

Definitely not 250/400N, different mounts altogether. See post on 500 brake orientation
